We look at the division of 78668730 by 80 
We're looking to find how many times 80 goes into 78668730.

Moving on to step 1:
If we divide 7 by 80, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 80

Moving on to step 2:
80 can be fit into 78 0 times, resulting in a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 80

Step 3:
80 goes into 786 9 times with a remainder of 66.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 720 from 786 and we're left with 66.
Fetch the next digit (6) from the dividend, attach it to 66 and continue: 666 / 80

Step 4:
The number 80 fits into 666 8 times, leaving a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
Subtract 640 from 666 to get 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 80

Step 5:
80 goes into 268 3 times with a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 983.0
The remainder is 28 after subtracting 240 from 268.
Include the next digit (7) from the dividend after 28, then repeat: 287 / 80

Going ahead to step 6:
The number 80 fits into 287 3 times, leaving a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 9833.0
Deduct 240 from 287 and we're left with 47.
Bring next digit (3) of the dividend behind the 47 and repeat the process: 473 / 80

Let's proceed to step 7:
473 divided by 80 is 5 with a remainder of 73.
Write down 5 as next digit of the result. 
Result so far: 98335.0
Subtract 400 from 473 to get 73.
Bring next digit (0) of the dividend behind the 73 and repeat the process: 730 / 80

Going ahead to step 8:
80 goes into 730 9 times with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 983359.0
The remainder is 10 after subtracting 720 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
80 goes into 100 1 times with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 983359.1
Deduct 80 from 100 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
200 divided by 80 is 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 983359.12
The remainder is 40 after subtracting 160 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
When dividing 400 by 80, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 983359.125
Subtract 400 from 400 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 983359.125
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 13:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 983359.125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 983359.125 with a balance of 0.0.
